How to set Navigation Drawer to be opened from right to left

In your main layout set your ListView gravity to right:

android:layout_gravity="right" 

Also in your code :

mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,            R.drawable.ic_drawer, R.string.drawer_open,            R.string.drawer_close) {    @Override    public boolean onOptionsItemSelected(MenuItem item) {        if (item != null && item.getItemId() == android.R.id.home) {            if (mDrawerLayout.isDrawerOpen(Gravity.RIGHT)) {                mDrawerLayout.closeDrawer(Gravity.RIGHT);            }             else {                mDrawerLayout.openDrawer(Gravity.RIGHT);            }        }        return false;    }};

hope it works :)

Add this code to manifest:

<application android:supportsRtl="true">

and then write this code on Oncreate:

getWindow().getDecorView().setLayoutDirection(View.LAYOUT_DIRECTION_RTL);

It works for me. ;)

SOLUTION

your_layout.xml:

<?xml version="1.0" encoding="utf-8"?><android.support.v4.widget.DrawerLayout    xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    xmlns:tools="http://schemas.android.com/tools"    android:id="@+id/drawer_layout"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:fitsSystemWindows="true"    tools:openDrawer="end">    <include layout="@layout/app_bar_root"        android:layout_width="match_parent"        android:layout_height="match_parent" />    <android.support.design.widget.NavigationView        android:id="@+id/nav_view"        android:layout_width="wrap_content"        android:layout_height="match_parent"        android:layout_gravity="end"        android:fitsSystemWindows="true"        app:itemTextColor="@color/black"        app:menu="@menu/activity_root_drawer" /></android.support.v4.widget.DrawerLayout>

YourActivity.java:

@Overrideprotected void onCreate(Bundle savedInstanceState) {//...toolbar = (Toolbar) findViewById(R.id.toolbar);drawer = (DrawerLayout) findViewById(R.id.drawer_layout);ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(            this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);drawer.setDrawerListener(toggle);toggle.syncState();toolbar.setNavigationOnClickListener(new View.OnClickListener() {        @Override        public void onClick(View v) {            if (drawer.isDrawerOpen(Gravity.RIGHT)) {                drawer.closeDrawer(Gravity.RIGHT);            } else {                drawer.openDrawer(Gravity.RIGHT);            }        }    });//...}
